摘　　要：通过盆栽试验,研究了土壤水分下限对番茄苗期、初花期和结果期的光合速率、蒸腾速率及果实品质、产量和水分利用效率的影响,试验结果表明,当土壤水分下限控制在苗期45%、初花期55%、结果期75%田间持水量范围内,可以提高果实品质,获得较高的产量和水分利用效率。With pot experiment, the effects of irrigation limits of soil moisture on tomato photosynthetic rate, transpiration rate, fruit quality, yield and water use efficiency were researched in different growth periods. The result showed that the yield and water use efficiency were the highest when lowest soil relative moisture 45% in seedling stage, 55% in flowering phase and 75% in bearing age appeared. And in this condition, it could get the higher quality fruit.
